BUNG.

SPECIFICATION forming part of Letters Patent No. 336,766, dated February 23I 1886.

Application tiled July 25, 1885. Serial No. 172,636. (No model.)

.T0 all whom. it may concern.:

Be it known that I, WILLIAM TAYLOR, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bungs, of which the following is a specification.

. This invention relates to bungs; and it consists in the peculiar construction and arrange` ment of the same, substantially as will be hereinafter more fully set forth and claimed.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring t-o the accompanying drawings, in which- Figure l is a sectional View of my device applied to a bushing and screwed down tightly. Fig. 2 isa similar view showing the bung loosened for Withdrawal, and Figs. 3, 4, and 5 are detail views of parts of my device.

a represents a bushing such as is commonly used in barrels of all kinds.

b represents the outer part of the bung, which is preferably of slightly-tapering form, to tit the bushing and obtain a firm seat, 'and is formed on its outer face with a recess, b', to receive and protect the screw, as shown. The inner face ol' this part is formed with a series of projecting teeth or lugs7 b2, as in the drawings, which teeth do not extend quite to the periphery of the bung, thus leaving a shoulder, b, against which rests a rubber or other elastic packing-ring, c, which surrounds the projections, as shown in Figs. I and 2.

The inner part, d, of this bung is ofjust the proper size to slip through the bushing, and its inner face is also formed with teeth or projections d,.which, when the parts are allin position, interlock 'with those upon the other part, b, and. allow of these parts being moved to and from each other, but do not permit of their being turned separately. It will be seen that the inner face of this part d is also formed around its projections with a shoulder or enlargement, d2; but this is beveled or rounded off, and the rubber packing-ring lies upon it, as shown.

A bolt or screw, e, is passed loosely through the upper part, b, and screwed through the lower part, d, and has upon its inner end a head, e', to prevent the part d from being detached.

-In practice the pieces b and d are screwed apart, as in Fig. 2, and the bung inserted in the bushing, the inner part just passing through and the packingring lying between the two parts upon their interlocking portions. as shown. The outer part having been pushed down till firmly seated, a common wrench is applied to the screw and the two parts of the bung thus drawn together. As they are thus drawn in the packingring is expanded around the beveled or rounded part d, and a tight joint formed,which not only retains theliquid in the barrel, but also effectually prevents the bung from being Withdrawn till the screw is` reversed and the two parts of the bung forced apart. To prevent any possible leakage around the head of the screw, I provide it with a rubber washer, as shown at f.

I do not desire to confine myself to the use of rubber as a packing-ring, but shall use any elastic and expansiblematerial found suitable for the purpose. Neither do I desire to be confined to the shape of the projecting teeth, as the object being simply to lock the two parts in engagement any form or number of projections will perform the object; but by using the large number shown I secure agood and nearly circular bearing for the packingring, to retain it in shape and position. It is evident that this `bung does not require any bushing, but may be used with equal effect without any bushing whatever, clamping directly upon the stave.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination, in abung, of the slightlytapered outer part formed with a recessed outer face and having projections on its inner face, the rounded or beveled inner part also formed with projections which interlock with those of the other part, an elastic packingring surrounding the interlocking portions, and a screw passed loosely through one part into the other, for drawing them together, substantially as and for the purpose set forth.

In testimony whereof I aitlx my signature Ico in presence of two witnesses.

WILLIAM TAYLOR.
